SYMPTOMS
To enhance the performance of access control list (ACL)
upgrades on public folders in a mixed Microsoft Exchange Server 5.5 and Microsoft Exchange 2000
Server environment, a cache mechanism for SID lookups was introduced in the following
Microsoft Knowledge Base article:
328906 Access control list upgrades cause slow public folder performance; fix requires Exchange 2000 Service Pack 3
By default, the original cache expired every hour. A
registry key, Lookup Sid Cache Expire, was added. Lookup Sid Cache Expire
permits the expiry time of the cache to be configured. The maximum value of
Lookup Sid Cache Expire was 6 hours. This design change increases the maximum
value of Lookup Sid Cache Expire to 24 hours.
